From: Haotian Zhang Date: Mon, 24 Nov 2025 01:58:52 +0000 (+0800) Subject: spi: amlogic-spifc-a1: Handle devm_pm_runtime_enable() errors X-Git-Tag: v6.18~4^2~2 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a90903c2a3c38bce475f46ea3f93dbf6a9971553;p=thirdparty%2Fkernel%2Flinux.git spi: amlogic-spifc-a1: Handle devm_pm_runtime_enable() errors devm_pm_runtime_enable() can fail due to memory allocation. The current code ignores its return value, potentially causing runtime PM operations to fail silently after autosuspend configuration. Check the return value of devm_pm_runtime_enable() and return on failure.
